Unless you are a plumbing professional, you probably aren’t familiar about sewer pipe relining. So, here’s a quick rundown of how sewer relining contractors in Sydney perform the procedure. Understanding the basics of this pipe rehabilitation procedure will help set the expectations and help you appreciate this innovative pipe repair procedure.
How Much Does Sewer Pipe Relining Cost?
The average cost of sewer pipe relining in Sydney is between $2,000 and $4,0000. In some cases, where longer sewer pipes need to be rehabilitated due to extensive wear and tear, crack, or missing points, customers may expect higher sewer relining cost. Compared to traditional pipe replacement that can cost up to $25,000, trenchless sewer relining is undeniably cost-effective. Customers don’t need to worry about additional cost of excavation and clean-up as relining does not involve any of these processes.
How Does Sewer Pipe Relining in Sydney Works?
Seamless sewer relining
Cured-in-place is one of the most common relining techniques used to repair damaged sewers and drains and homes in Sydney. It is also cheaper than traditional pipe replacement. The process involves seamless resin application that restores the impermeability of your existing pipes, eliminating leaks, and future deterioration while improving flow efficiency.
Epoxy resin installation
For smaller leaks, bursts, and junctions, sewer relining contractors will inject epoxy resin through clean outs and drains. Epoxy resin is a highly durable lining material that guarantees efficiency for up to 50 years. Before any relining is done, experts will begin by drying the pipes by sandblasting the inner walls with highly pressurised air and a mineral that eliminates corrosion and oxidation. This process also prepares the wall for relining. Epoxy resin installation is applicable to restore all types of pipes, including galvanised iron, copper, steel, and PVC pipes.
CCTV pipe inspection
Before any trenchless sewer relining happens, sewer relining contractors will begin by giving your drain or sewer lines a comprehensive visual inspection. The CCTV pipe inspection is a minimally invasive means of assessing the location and damage within pipes. The degree of deterioration, pipe diameter, and effectiveness of installation are all factored in to develop an effective sewer relining plan.
What are the Benefits of Obtaining the Services of Professional Sewer Relining Contractors?
- Prevents root intrusion and minimises chance of leakage
- Improves flow
- No excavation, digging, or landscape disruption
- Increased structural strength and integrity of existing pipes

When Do You Need Trenchless Sewer Relining?
Aging sewer lines
Old residential and commercial properties in Sydney are equipped with cast iron and clay pipes. These pipelines are prone to cracking and corrosion, both of which leads to cracks, leaks, joints and root intrusions.
Almost half of blocked sewer drain issues are caused by root intrusion. The intrusion of root systems into sewer systems can be attributed to older pipes or worn-out sewer lines . Other factors that result in damage to old pipes are shallow pipes, small-diameter pipes, and presence of fast-growing species in a property.
One of the main selling points of sewer relining is that it protects pipes from further root intrusions in joints and cracks. Epoxy resin is used to further strengthen pipes and protect its roots invading the interior walls of sewer lines.
Sewer lines calcification
The calcium found in water finds its way deposited along the inner walls of sewer pipes. The build-up of calcium results in a calcified layer that clogs up an entire sewerage system. If your property uses hard water, this is a common cause of damaged and clogged up pipes.
Epoxy resin relining is highly resistant to corrosion, abrasion, and calcium deposits. It protects the pipeline from future calcification.
Ground movement has an impact on sewer line integrity. Seismic activities can cause sewer line damage. Even minor seismic activities can create small cracks that may result in major structural damage when left unnoticed.
Sewer relining contractors utilise the jointless, pulled-in-place relining technique to keep your pipelines durable and resistant to external stressors, including seismic activities. The liner inserted into a sewer line is highly saturated with epoxy resin. An internal rubber bladder is also inserted into the line, and then inflated, making it easier for the resin to adhere along damaged sections of drain and sewer pipes. After a few hours of curing, you can resume using your drains and sewer lines without worry.
